Tip of the Red Giant Branch Distances with JWST. II. I-band Measurements in a Sample of Hosts of 10 Type Ia Supernova Match HST Cepheids

The Astrophysical Journal
The Hubble Tension, a >5 σ discrepancy between direct and indirect measurements of the Hubble constant ( H _0 ), has persisted for a decade and motivated intense scrutiny of the paths used to infer H _0 .

The Effect of a Nonuniversal Extinction Curve on the Wesenheit Function and Cepheid Distances

The Astrophysical Journal Letters
The Wesenheit function is widely used to reduce the effects of interstellar reddening in distance measurements. Its construction, however, relies on the assumption of a universal extinction curve and on fixed values of the total-to-selective extinction ...
